Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12186, here are decompositions:

23 + 12163 = 12186
29 + 12157 = 12186
37 + 12149 = 12186
43 + 12143 = 12186
67 + 12119 = 12186
73 + 12113 = 12186
79 + 12107 = 12186
89 + 12097 = 12186

Showing the first eight; more decompositions exist.
